Abstract

The invention relates to a feedstuff additive prepared from bacillus antibacterial peptides and bacillus probiotics and a using method thereof in feedstuff, and belongs to the field of feedstuff additives. The compound feedstuff additive is prepared from bacillus antibacterial peptides and bacillus probiotics, wherein the content of bacillus antibacterial peptides in per gram of compound feedstuff additive is 2-20 mg, and the content of bacillus probiotics in per gram of compound feedstuff additive is 1.0-5.0*109 cfu. The feedstuff additive can be used as an antibiotic substituted product, antibiotic residues are removed, the quality of meat, eggs and milk is improved, and the feedstuff additive can be used for preventing and treating kinds of animal diarrhea, improving production performance of animals, immunity and disease resistance and increasing the feedstuff conversion rate. The additive is a green feedstuff additive and is beneficial to improving the quality of livestock and poultry products and health of humans.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a compound feed additive. Background technique [0002] The extensive use of antibiotics as additives in feed not only causes the imbalance of intestinal microorganisms in livestock and poultry, but also easily leads to antibiotic residues, reduces the quality of livestock products, and seriously affects the export of livestock products and human health. In order to eliminate the negative effects of antibiotic use, the World Health Organization calls on countries to take urgent measures. The United States, the United Kingdom and many other countries have formulated corresponding strategies. According to the spirit of EU No. 70 / 524, traditional antibiotics will be canceled one by one in a very short period of time. Antibiotics such as avomycin, spiramycin, bacitracin zinc, and tylosin phosphate are involved in the transmission of drug resistance. It is also used as a feed...
